Sir Cumference and the Dragon of Pi, a Math Adventure

by Cindy Neuschwander, illustrated by Wayne Geehan

In Sir Cumference and the Dragon of Pi, a Math Adventure, Radius (the name is referred to but not described in math terms) saves his father’s life after accidentally turning him into a fire breathing dragon.  Of course, a math formula is the reason for the solution.  Did you know Sir Cumference named Pi in this story?  Did you know this story tells how the math formula for ∏ was discovered?  This is a fictional story but the author’s purpose is achieved when children remember this math lesson.

This is my free PDF work page set which is also for the other Sir Cumference book I have reviewed on this blog, Sir Cumference and the Great Knight of Angleland.

Did you know March 14 (think about it) is Pi Day in many schools?  At school pies are perhaps served at least in the teacher’s lounge on this day to accompany this story and the learning of this formula:  circumference divided by diameter = Pi or ∏

I’m seeing the book for the first time but I have heard about it at workshops and seen it mentioned in articles. I teach a Grade 4 class but I think my students will benefit from it.
Thanks for the offer.

Audey, yes it will work with grade four or five. They will understand the math part more than the younger children. Thank you for writing. Carolyn
